This article about ice was published in a magazine in 1875. There is some
mention of how ice was harvested from ponds and rivers during the
winter months, but the article is mostly about how ice was artificially made, and
there is even a picture of Ferdinand Carré's ice machine! —fadedpages.com
ICE.
Ice is one thing in which Americans revel in the summer-time.
No other nation lays in such a stock, or so peremptorily demands
an abundant supply. American ice is sold in London, Calcutta, and
a hundred places between the two. Usually the ice is "harvested"
on ponds or rivers in the North, and the business has created a
whole set of peculiar contrivances for scraping off the surface
and removing snow; sawing the sheet into blocks without quite
detaching; splitting them off; floating them to the hoist;
elevating them by endless chains; delivering them to the men who
stow them in a solid mass occupying the whole interior of the
barn.
More specially noticeable, however, are the machines for
congealing water into ice, and which are commencing to work at a
price below that at which the ice can be gathered and transported.
Speaking in short terms, there are four modes of making
ice—vaporization, radiation, liquefaction, and sudden reduction of
pressure.
Vaporization in a partial vacuum formed the basis of Dr.
Cullen's attempts in 1755; in 1777 Nairne used sulphuric acid to
absorb the vapor rising from water in an exhausted receiver.
Ferdinand Carré's apparatus is on this principle, and is used
to produce the carafes frappées so common in Parisian
restaurants. In the continuous operation of Ferdinand Carré
ammonia is employed as being more volatile than water, and under
ordinary atmospheric pressure permanently gaseous. The apparatus
is somewhat complicated, but effective. The water is in cans in a
bath of uncongealable liquid, cooled by zigzag tubes, into which
the liquid ammonia is conducted to expand, and thereby convert the
sensible heat of the surrounding bath into latent, due to its
assumption of the gaseous condition. There are many modifications
of the vaporization principle, but no room to tell of them.

Liquefaction is another mode, and snow and ice are used in
connection with salts. Combinations of salts are also used.
Machines are also used in which air is exhausted by a steam-engine
from a receiver, the expansion of liquid into a gaseous condition
drawing heat from the water sufficient to congeal it.
